Add IPFS deploy pipeline

[mprasanjith]

Description

• Refactor CI / CD pipeline to deploy to IPFS / Filecoin through Web3.storage.
• Publish preview deploys as Github Environments.
• Add cleanup pipeline to deactivate Github Environment for closed PRs.
• Switch to hash routing for IPFS compatibility.

Caveats

Currently IPFS does not support SPA browser routing, which means we have to switch to hash routing. A solution might be landing to IPFS in the future.

Prerequisites

This PR should not be merged until we set the WEB3_STORAGE_TOKEN secret in repo settings.

Motivation and Context

This will let us;

• move away from Netlify / GitHub pages for dev deployments.
• continue having preview URLs for all PRs the same way Netlify provides today.

How Has This Been Tested?

Tested from a forked Github repo.

Aside from the failing build currently ... (Hopefully a small issue)
This is so cool and definitely something we should share with the rest of DXdao!
Maybe you could bring it up on the next developer call @mprasanjith

[mprasanjith]

The build is failing due to the missing WEB3_STORAGE_TOKEN secret, so once we have that added we should be good to go.

This definitely is something we can share with other teams, let's discuss in the next Dev call.

PS: Just figured I had the wrong diagnosis for the failing build. I put the PR from a fork of this repo. That means the upstream GitHub pipeline on this repo is not able to access my fork to do the CI build. Shouldn't be a problem once merged.
